How To Coordinate An International Search

Nine countries are involved in the search for missing Malaysia Airlines flight 370, with dozens of planes and ships scanning the area where the flight may have gone down.

There is no designated leader in the search. Aviation officials say that the official investigation can not begin until the aircraft is located. It's expected to be found in either Malaysian or Vietnamese waters.
